Stefán Jökull has been a professional programmer for over 20 years, although he wrote his first BASIC program on an old Amstrad CPC 464 way back in 1986. He works remotely from Iceland where he focuses on improving Have I Been Pwned. He has a lot of experience with systems that require attention to details and have high customer impact.

Stefán is also a Microsoft MVP, a member of the .NET Foundation, and specializes in all things .NET with a focus on performance, security, and analytics/telemetry.

When he's not working, he enjoys time with the family, working on OSS software, building Lego sets and having the occasional beer when meeting fellow developers.
